In an example, the aspects may include identifying one or more groups of CORESETs, each of the one or more groups of CORESETs include at least one half-duplex (HD) CORESET, full-duplex (FD) CORESET, or combination thereof; receiving one or more of the at least one HD CORESET and FD CORESET of the one or more groups of CORESETs from a network entity; performing a BFD measurement procedure with a reference signal associated with at least one CORESET of the one or more groups of CORESETs; and detecting whether a cell level failure event or a group level failure event is triggered based on the BFD measurement procedure.

BACKGROUND

Aspects of the present disclosure relate generally to wirelesscommunication systems, and more particularly, to beam failure detection(BFD) associated with mixed control resource sets (CORESETs) for halfduplex transmission mode and full duplex transmission mode if radio linkmanagement (RLM)/BFD reference signal (RS) is not explicitly configuredby radio resource control (RRC) signaling

Wireless communication systems are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be multiple-accesssystems capable of supporting communication with multiple users bysharing the available system resources (e.g., time, frequency, andpower). Examples of such multiple-access systems include code-divisionmultiple access (CDMA) systems, time-division multiple access (TDMA)systems, frequency-division multiple access (FDMA) systems, andorthogonal frequency-division multiple access (OFDMA) systems, andsingle-carrier frequency division multiple access (SC-FDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. For example, a fifth generation (5G)wireless communications technology (which can be referred to as NewRadio (NR)) is envisaged to expand and support diverse usage scenariosand applications with respect to current mobile network generations. Inan aspect, 5G communications technology can include: enhanced mobilebroadband addressing human-centric use cases for access to multimediacontent, services and data; ultra-reliable-low latency communications(URLLC) with certain specifications for latency and reliability; andmassive machine type communications, which can allow a very large numberof connected devices and transmission of a relatively low volume ofnon-delay-sensitive information.

For example, for various communications technology such as, but notlimited to NR, complex determination needs to be made for implicit BFDwith mixed half duplex CORESET(s) and FD CORESET(s) if RLM/BFD RS is notexplicitly configured. Thus, improvements in wireless communicationoperations may be desired.

DETAILED DESCRIPTION

Various aspects are now described with reference to the drawings. In thefollowing description, for purposes of explanation, numerous specificdetails are set forth in order to provide a thorough understanding ofone or more aspects. It may be evident, however, that such aspect(s) maybe practiced without these specific details.

The described features generally relate to beam failure detection (BFD)associated with mixed control resource sets (CORESETs) for half duplextransmission mode and full duplex transmission mode if radio linkmanagement (RLM)/BFD reference signal (RS) is not explicitly configuredby radio resource control (RRC) signaling. In an aspect, a userequipment (UE) and a base station may communicate with each other usingTx and Rx beams. For example, a beam may be a downlink beam (e.g., onwhich information may be conveyed from the base station to the UE) or anuplink beam (e.g., on which information may be conveyed from the UE tothe base station).

A user equipment (UE) and/or a base station may communicate in a fullduplex mode in which uplink communication and downlink communication isexchanged in a same frequency band, or partially overlapped frequencyband, or separate frequency bands at overlapping times orsimultaneously. The UE and the base station may exchange communicationusing a downlink and uplink beam pair. The UE may perform ongoing uplinkor downlink transmissions at different times in a half-duplex mode(either via an uplink beam or via a downlink beam). A full duplex linkmay provide increased scalability of data rates on the link incomparison to a half duplex link. Full duplex capability may be presentat either the gNB or the UE or both. For example, at the UE, uplinktransmissions may occur from one panel and downlink reception may occurin another panel. The full duplex capability may be conditional on beamseparation.

In a full duplex link, different antenna elements, sub-arrays, orantenna panels of a wireless communication device may simultaneously orcontemporaneously perform uplink and downlink communication. Thebenefits of full duplex communications include latency reduction (e.g.,a possibility to receive downlink signals in uplink only slots whichenables latency savings), spectrum efficiency enhancement (e.g., percell and/or per UE), and more efficient resource utilization.

A UE may monitor reference signals transmitted by a base station todetect one or more beam failures. A beam failure may occur due tochanging channel conditions, obstacles (e.g., physical barriers such asbuildings and/or walls that inhibit the transmission of wirelesssignals), distance from the base station transmitting the beam,interference, and/or the like. When a reference signal of a first set ofbeams fails to satisfy a threshold (e.g., a Qout threshold (e.g., theQout threshold corresponds to 10% block error rate (BLER) of ahypothetical PDCCH transmission taking into account the PCFICH errors)and/or the like) on a particular number of one or more monitoringoccasions, the UE may identify a beam failure. The UE may perform a beamrecovery procedure upon detecting a beam failure, as described in detailelsewhere herein. The reference signals monitored by the UE may beexplicitly configured by the base station. If not configured, referencesignals monitored by the UE may be implicitly indicated by the sameQCLed RSs as a control channel, which may be identified by a CORESET.

Full duplex communication may present certain challenges in comparisonto half duplex communication. For example, a wireless communicationdevice (e.g., a UE or a base station) may experience self-interferencebetween an uplink beam and a downlink beam of a full duplex link orbetween components of the wireless communication device. Thisself-interference may complicate the monitoring of reference signals todetect beam failure. Furthermore, self-interference, cross-correlation,and/or the like, may occur in a full duplex link that may not occur in ahalf duplex link, so the RSs associated with a CORESET for monitoringbeam failure in a half duplex link (e.g., the resource allocations, thethresholds, and/or the like) may not be suitable or ideal for monitoringbeam failure in a full duplex link due to such self-interference orcross-correlation.

As such, the present disclosure relates to BFD associated with mixedCORESETs for half duplex transmission mode and full duplex transmissionmode if RLM/BFD RS is not explicitly configured by RRC signaling.Specifically, the present disclosure provides for enhancingbi-directional communication between a UE and a network entity. In anaspect, the present disclosure provides apparatus and methods foridentifying one or more groups of CORESETs, each of the one or moregroups of CORESETs include at least one HD CORESET, FD CORESET, orcombination thereof; receiving one or more of the at least one HDCORESET and FD CORESET of the one or more groups of CORESETs from anetwork entity; performing a BFD measurement procedure with a referencesignal associated with at least one CORESET of the one or more groups ofCORESETs; and detecting whether a cell level failure event or a grouplevel failure event is triggered based on the BFD measurement procedure.In an aspect, the present disclosure provides apparatus and methods fordetermining one or more groups of CORESETs, each of the one or moregroups of CORESETs include at least one HD CORESET, FD CORESET, orcombination thereof; transmitting one or more of the at least one HDCORESET and FD CORESET of the one or more groups of CORESETs to a UE;and receiving a beam failure recovery request from the UE based on atleast one of a cell level failure event or a group level failure eventthat is triggered based on a BFD measurement procedure at the UE.

The described features will be presented in more detail below withreference to FIGS. 1-6 .

As used in this application, the terms “component,” “module,” “system”and the like are intended to include a computer-related entity, such asbut not limited to hardware, software, a combination of hardware andsoftware, or software in execution. For example, a component may be, butis not limited to being, a process running on a processor, a processor,an object, an executable, a thread of execution, a program, and/or acomputer. By way of illustration, both an application running on acomputing device and the computing device can be a component. One ormore components can reside within a process and/or thread of executionand a component can be localized on one computer and/or distributedbetween two or more computers. In addition, these components can executefrom various computer readable media having various data structuresstored thereon. The components can communicate by way of local and/orremote processes such as in accordance with a signal having one or moredata packets, such as data from one component interacting with anothercomponent in a local system, distributed system, and/or across a networksuch as the Internet with other systems by way of the signal. Softwareshall be construed broadly to mean instructions, instruction sets, code,code segments, program code, programs, subprograms, software modules,applications, software applications, software packages, routines,subroutines, objects, executables, threads of execution, procedures,functions, etc., whether referred to as software, firmware, middleware,microcode, hardware description language, or otherwise.

Techniques described herein may be used for various wirelesscommunication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, andother systems. The terms “system” and “network” may often be usedinterchangeably. A CDMA system may implement a radio technology such asCDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000covers IS-2000, IS-95, and IS-856 standards. IS-2000 Releases 0 and Aare commonly referred to as CDMA2000 1×, 1×, etc. IS-856 (TIA-856) iscommonly referred to as CDMA2000 1×EV-DO, High Rate Packet Data (HRPD),etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. ATDMA system may implement a radio technology such as Global System forMobile Communications (GSM). An OFDMA system may implement a radiotechnology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA),IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM™, etc.UTRA and E-UTRA are part of Universal Mobile Telecommunication System(UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are newreleases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, andGSM are described in documents from an organization named “3rdGeneration Partnership Project” (3GPP). CDMA2000 and UMB are describedin documents from an organization named “3rd Generation PartnershipProject 2” (3GPP2). The techniques described herein may be used for thesystems and radio technologies mentioned above as well as other systemsand radio technologies, including cellular (e.g., LTE) communicationsover a shared radio frequency spectrum band. The description below,however, describes an LTE/LTE-A system for purposes of example, and LTEterminology is used in much of the description below, although thetechniques are applicable beyond LTE/LTE-A applications (e.g., to fifthgeneration (5G) NR networks or other next generation communicationsystems).

The following description provides examples, and is not limiting of thescope, applicability, or examples set forth in the claims. Changes maybe made in the function and arrangement of elements discussed withoutdeparting from the scope of the disclosure. Various examples may omit,substitute, or add various procedures or components as appropriate. Forinstance, the methods described may be performed in an order differentfrom that described, and various steps may be added, omitted, orcombined. Also, features described with respect to some examples may becombined in other examples.

Various aspects or features will be presented in terms of systems thatcan include a number of devices, components, modules, and the like. Itis to be understood and appreciated that the various systems can includeadditional devices, components, modules, etc. and/or may not include allof the devices, components, modules etc. discussed in connection withthe figures. A combination of these approaches can also be used.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) can includebase stations 102, UEs 104, an Evolved Packet Core (EPC) 160, and/or a5G Core (5GC) 190. The base stations 102, which may also be referred toas network entities, may include macro cells (high power cellular basestation) and/or small cells (low power cellular base station). The macrocells can include base stations. The small cells can include femtocells,picocells, and microcells. In an example, the base stations 102 may alsoinclude gNBs 180, as described further herein.

In one example, some nodes such as base station 102/gNB 180, may have amodem 240 and a communicating component 242 which may (either incombination and/or separately) be configured for determining andtransmitting one or more groups of CORESETs 248 including at least oneof HD CORESET 250 and FD CORESET 252, or combination thereof, asdescribed herein. Though a base station 102/gNB 180 is shown as havingthe modem 240 and communicating component 242, this is one illustrativeexample, and substantially any node or type of node may include a modem240 and communicating component 242 for providing correspondingfunctionalities described herein.

In one example, a UE, such as UE 104, may have a modem 340 and acommunicating component 342 which may (either in combination and/orseparately) be configured for reporting of multiple candidate panels permeasured downlink reference signals, as described herein. For example,UE 104 in conjunction with modem 340 and/or communicating component 342may receive one or more of the at least one HD CORESET 250 and FDCORESET 252 of the one or more groups of CORESETs 248 from a basestation 102, perform a BFD measurement procedure and transmit a BFDreport indicating multiple candidate panels to base station 102. Thougha UE 104 is shown as having the modem 340 and communicating component342, this is one illustrative example, and substantially any node ortype of node may include a modem 340 and communicating component 342 forproviding corresponding functionalities described herein.

The base stations 102 configured for 4G LTE (which can collectively bereferred to as Evolved Universal Mobile Telecommunications System (UMTS)Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC160 through backhaul links 132 (e.g., using an S1 interface). The basestations 102 configured for 5G NR (which can collectively be referred toas Next Generation RAN (NG-RAN)) may interface with 5GC 190 throughbackhaul links 184. In addition to other functions, the base stations102 may perform one or more of the following functions: transfer of userdata, radio channel ciphering and deciphering, integrity protection,header compression, mobility control functions (e.g., handover, dualconnectivity), inter-cell interference coordination, connection setupand release, load balancing, distribution for non-access stratum (NAS)messages, NAS node selection, synchronization, radio access network(RAN) sharing, multimedia broadcast multicast service (MBMS), subscriberand equipment trace, RAN information management (RIM), paging,positioning, and delivery of warning messages. The base stations 102 maycommunicate directly or indirectly (e.g., through the EPC 160 or 5GC190) with each other over backhaul links 134 (e.g., using an X2interface). The backhaul links 132, 134 and/or 184 may be wired orwireless.

The base stations 102 may wirelessly communicate with one or more UEs104. Each of the base stations 102 may provide communication coveragefor a respective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacro cells may be referred to as a heterogeneous network. Aheterogeneous network may also include Home Evolved Node Bs (eNBs)(HeNBs), which may provide service to a restricted group, which can bereferred to as a closed subscriber group (CSG). The communication links120 between the base stations 102 and the UEs 104 may include uplink(UL) (also referred to as reverse link) transmissions from a UE 104 to abase station 102 and/or downlink (DL) (also referred to as forward link)transmissions from a base station 102 to a UE 104. The communicationlinks 120 may use multiple-input and multiple-output (MIMO) antennatechnology, including spatial multiplexing, beamforming, and/or transmitdiversity. The communication links may be through one or more carriers.The base stations 102/UEs 104 may use spectrum up to Y MHz (e.g., 5, 10,15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrieraggregation of up to a total of Yx MHz (e.g., for x component carriers)used for transmission in the DL and/or the UL direction. The carriersmay or may not be adjacent to each other. Allocation of carriers may beasymmetric with respect to DL and UL (e.g., more or less carriers may beallocated for DL than for UL). The component carriers may include aprimary component carrier and one or more secondary component carriers.A primary component carrier may be referred to as a primary cell (PCell)and a secondary component carrier may be referred to as a secondary cell(SCell).

In another example, certain UEs 104 may communicate with each otherusing device-to-device (D2D) communication link 158. The D2Dcommunication link 158 may use the DL/UL WWAN spectrum. The D2Dcommunication link 158 may use one or more sidelink channels, such as aphysical sidelink broadcast channel (PSBCH), a physical sidelinkdiscovery channel (PSDCH), a physical sidelink shared channel (PSSCH),and a physical sidelink control channel (PSCCH). D2D communication maybe through a variety of wireless D2D communications systems, such as forexample, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154 in a 5 GHz unlicensed frequency spectrum. Whencommunicating in an unlicensed frequency spectrum, the STAs 152/AP 150may perform a clear channel assessment (CCA) prior to communicating inorder to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same 5 GHz unlicensedfrequency spectrum as used by the Wi-Fi AP 150. The small cell 102′,employing NR in an unlicensed frequency spectrum, may boost coverage toand/or increase capacity of the access network.

A base station 102, whether a small cell 102′ or a large cell (e.g.,macro base station), may include an eNB, gNodeB (gNB), or other type ofbase station. Some base stations, such as gNB 180 may operate in atraditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies,and/or near mmW frequencies in communication with the UE 104. When thegNB 180 operates in mmW or near mmW frequencies, the gNB 180 may bereferred to as an mmW base station. Extremely high frequency (EHF) ispart of the RF in the electromagnetic spectrum. EHF has a range of 30GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters.Radio waves in the band may be referred to as a millimeter wave. NearmmW may extend down to a frequency of 3 GHz with a wavelength of 100millimeters. The super high frequency (SHF) band extends between 3 GHzand 30 GHz, also referred to as centimeter wave. Communications usingthe mmW/near mmW radio frequency band has extremely high path loss and ashort range. The mmW base station 180 may utilize beamforming 182 withthe UE 104 to compensate for the extremely high path loss and shortrange. A base station 102 referred to herein can include a gNB 180.

The EPC 160 may include a Mobility Management Entity (MME) 162, otherMMEs 164, a Serving Gateway 166, a Multimedia Broadcast MulticastService (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC)170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be incommunication with a Home Subscriber Server (HSS) 174. The MME 162 isthe control node that processes the signaling between the UEs 104 andthe EPC 160. Generally, the MME 162 provides bearer and connectionmanagement. All user Internet protocol (IP) packets are transferredthrough the Serving Gateway 166, which itself is connected to the PDNGateway 172. The PDN Gateway 172 provides UE IP address allocation aswell as other functions. The PDN Gateway 172 and the BM-SC 170 areconnected to the IP Services 176. The IP Services 176 may include theInternet, an intranet, an IP Multimedia Subsystem (IMS), a PS StreamingService, and/or other IP services. The BM-SC 170 may provide functionsfor MBMS user service provisioning and delivery. The BM-SC 170 may serveas an entry point for content provider MBMS transmission, may be used toauthorize and initiate MBMS Bearer Services within a public land mobilenetwork (PLMN), and may be used to schedule MBMS transmissions. The MBMSGateway 168 may be used to distribute MBMS traffic to the base stations102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN)area broadcasting a particular service, and may be responsible forsession management (start/stop) and for collecting eMBMS relatedcharging information.

The 5GC 190 may include a AMF 192, other AMFs 193, a Session ManagementFunction (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 maybe in communication with a Unified Data Management (UDM) 196. The AMF192 can be a control node that processes the signaling between the UEs104 and the 5GC 190. Generally, the AMF 192 can provide QoS flow andsession management. User Internet protocol (IP) packets (e.g., from oneor more UEs 104) can be transferred through the UPF 195. The UPF 195 canprovide UE IP address allocation for one or more UEs, as well as otherfunctions. The UPF 195 is connected to the IP Services 197. The IPServices 197 may include the Internet, an intranet, an IP MultimediaSubsystem (IMS), a PS Streaming Service, and/or other IP services.

The base station 102 providesan access point to the EPC 160 or 5GC 190 for a UE 104. Examples of UEs104 include a cellular phone, a smart phone, a session initiationprotocol (SIP) phone, a laptop, a personal digital assistant (PDA), asatellite radio, a positioning system (e.g., satellite, terrestrial), amultimedia device, a video device, a digital audio player (e.g., MP3player), a camera, a game console, a tablet, a smart device, robots,drones, an industrial/manufacturing device, a wearable device (e.g., asmart watch, smart clothing, smart glasses, virtual reality goggles, asmart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)),a vehicle/a vehicular device, a meter (e.g., parking meter, electricmeter, gas meter, water meter, flow meter), a gas pump, a large or smallkitchen appliance, a medical/healthcare device, an implant, asensor/actuator, a display, or any other similar functioning device.Some of the UEs 104 may be referred to as IoT devices (e.g., meters,pumps, monitors, cameras, industrial/manufacturing devices, appliances,vehicles, robots, drones, etc.).

The described features generally relate to BFD associated with mixedCORESETs for half duplex transmission mode and full duplex transmissionmode if RLM/BFD RS is not explicitly configured by RRC signaling. In anaspect, two groups of CORESETs may be established. For example, thefirst group may include only HD CORESET(s) and the second group mayinclude only FD CORESET(s). In this example, four CORESETs may beestablished. The first group may include two CORESETs which correspondto HD CORESETs while the second group may include the other two CORESETscorresponding to the FD CORESETs. The groups may be predetermined at thegNB and/or the UE.

In another example, two groups of mixed HD and FD CORESETs may bedefined. In this example, four CORESETs may be established. The firstgroup may include two CORESETs which correspond to a FD CORESET and a HDCORESET. Similarly, the second group may include two CORESETs whichcorrespond to a FD CORESET and a HD CORESET.

In an aspect, for channel state information-reference signal (CSI-RS) asthe BFD RS, the UE may determine the TCI state (e.g., CSI-RS beam) quasico-located (QCLed) type D in the corresponding HD or FD CORESET ID. TheUE may perform downlink beam BFD/RRM measurements at correspondingCSI-RS resource locations for the CSI-RS beam corresponding to the TCIstate. For FD BFD RS, other than CSI-RS, the UL beam needs to bedetermined (e.g. a sounding reference signal (SRS) beam that is pairedwith the CSI-RS beam in the corresponding FD CORESET ID). Subsequently,the UE may perform UL beam (e.g., self-interference) BFD/RRMmeasurements to measure the SRS ID beam in the configured resources. ForHD mode, with one or more DL CSI-RS beams, the UE may calculate L1-RSRPsfor BFD/RRM. For FD mode, with one or more paired DL CSI-RS and UL SRSbeam pairs, UE may calculate L1-SINRs for BFD/RRM.

In an aspect, full beam failure may correspond to a cell level failureand partial beam failure may correspond to a group level failure. Forexample, for two groups of CORESETs, both groups' failure may beindicated as full beam failure which may be triggered as an event of acell level failure. Further, the HD CORESET group may be defined as apartial beam failure, which may be triggered as an event of a grouplevel failure. Additionally, the FD CORESET group may be defined aspartial beam failure as well, which may be triggered an event of as agroup level failure.

In an aspect, for one of the two groups of CORESETs, the one group'sfailure may be indicated as full beam failure which may be triggered asan event of a cell level failure. For example, HD CORESET group may bedefined as full beam failure, which may be triggered as an event of acell level failure. Additionally, the FD CORESET group may be defined aspartial beam failure, triggered as an event of a group level failure. Inanother example, the FD CORESET group may be defined as full beamfailure, which may be triggered as an event of a cell level failure.Further, the HD CORESET group may be defined as partial beam failure,which may be triggered as an event of a group level failure. Thedetermination for how each aspect may be defined may be pre-determined.If bot aspects are enabled, then the gNB may signal the determinationfor BFD.
